Welcome Email - Buddypress? First Login

So I'm using the excellent Welcome Pack to redirect users the first time the login to their profile page. Now, I want to also kick off an HTML email to them welcoming them to the site and giving them suggestions to visit parts of the site and stuff.

I'll be the first to admit, my PHP-Foo is not strong (yet) -- but I'm learning. I am figuring there's a way to sort of latch on to that process of redirection to kick off some sort of email thing.

Am I heading down the right road? Anyone know a better way? Thanks!
